Apple is a kind and tidy host, not very communicative, but she replies to any question that you would have.
The apartment is as described: simple place in a local area (III)
The only issue was there wasn't any wifi in the room (as described in the announcement's items), luckly I bought a 4G sim card in the airport so I didn't had any problems with internet (since it's not that expensive, it's good to buy one, the one I bought was from TrueMove H). Otherside, if you need Internet and you didn't bought a sim card, you can go to nearby 7-Eleven that they have free WiFi.
To reach the place, if you want to go by cheapest way, you need to get the Airport Link to PhayaThai and there transfer to BTS SkyTrain that is going to Mo Chit, get off at the Saphan Khwai Station, from there you can trace a route by foot by GoogleMaps. It's around 20min walking from the station.
If you need to wash your clothes, you can use coin loundry in the store that is in the left of the lobby.
The neighborhood is very convenient with a lot of street food stalls that is much more cheaper than the ones in downtown area.
In weekends there is the JJ Market that is very good to visit.
And the Big C nearby Saphan Khawai is a great supermarket to buy some food and other candies.
